Video Compositing System Posture Matching via Dynamic Still Images
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video recording systems for compositing struggle to ensure natural continuity and accurate posture matching in composited videos, leading to unnatural discontinuities and difficulties in gestural matching.
Innovation Solution
A video recording system and method that includes a first monitor displaying a live video of the user and a basic posture still image, a recording apparatus, and an image controller that manages the basic posture still images and live video, changing the still images when specific conditions are met to guide the user's posture and ensure compositional continuity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If basic posture still images are displayed to guide user posture during video recording, then posture matching accuracy is improved, but device complexity increases
Solution Approach 1:
The system segments the guidance function into discrete basic posture still images that can be independently selected and displayed. Each still image represents a specific gesture or posture state, allowing the system to provide targeted visual guidance without requiring complex real-time posture analysis hardware.
Solution Approach 2:
The image controller performs multiple functions: it manages the display of basic posture still images, monitors user videos, determines posture matching, and provides visual feedback. This multi-functionality consolidates what would otherwise require separate specialized devices into a single controller.
2Manufacturing precision
If the system monitors and manages multiple user videos from different recording apparatuses, then compositing quality is improved, but loss of time increases
Solution Approach 1:
The system performs preliminary actions by pre-managing and organizing user videos from multiple recording apparatuses before compositing. The image controller divides videos into gesture units and preset length units in advance, preparing them for efficient compositing operations.
Solution Approach 2:
The system creates and manages copies of user videos from different recording apparatuses, allowing simultaneous processing and comparison of multiple video streams. This copying approach enables parallel processing of gesture units from different sources without time loss.
3Speed
If the image controller frequently updates basic posture still images based on image conversion conditions, then responsiveness is improved, but use of energy increases
Solution Approach 1:
The image controller updates basic posture still images periodically based on image conversion conditions rather than continuously. The system checks for conditions such as gesture unit transitions or preset time intervals, updating displays only when necessary to maintain responsiveness while conserving energy.
4Ease of operation
If the system provides detailed guidance on compositing criteria including posture change portions, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The image controller acts as an intermediary that translates complex compositing criteria into user-friendly visual guidance. It processes detailed posture requirements and converts them into displayed basic posture still images and notifications, simplifying the interaction for users while maintaining system sophistication.

AI summary
A video recording system for compositing includes a first monitor which is positioned in a gaze area of a user and is for outputting a live video of the user and a basic posture still image displayed to be superimposed on the live video of the user, a recording apparatus for recording the user, and an image controller for transmitting the basic posture still image and the live video of the user to the first monitor on the basis of a user video transmitted from the recording apparatus and changing the basic posture still image transmitted to the first monitor when an image conversion condition is met while recording the live video of the user.
